Melting Ice

Problem Scenario

Can ice melt faster if it's shaped differently?

Broad Question

Is there a way to make ice melt faster?

Specific Question

Does the shape of ice affect the rate it melts at?

Hypothesis

Yes, the shape of the ice affects the rate it melts at.

Graph of Hypothesis

Variables

Independent Variable: Shape of ice

Dependent Variable: Time melting

Variables That Need To Be Controlled:Volume of ice

Temperature of ice
Temperature of while melting
Anything getting in the water or ice

General Plan

The same volume of water will be frozen into different shapes and timed for how long it takes the ice to melt.

Potential Problems And Solutions

Safety Or Environmental Concerns

Experimental Design

What is your experimental unit?

The experimental unit for this project is the time it takes the ice to melt.

Number Of Trials:

There will be four different shapes of ice and they will each be melted three times.

Number Of Subjects In Each trial:

There are four different shapes in each trial.

Number of Observations:

There will be three different observations for each shape of ice.

When data will be collected

Looking for an actual date or dates here. This is requiring you to commit to your project.

Where will data be collected?:

This data is going to be collected in Mr. Littlefield's science room.

Conclusion

Discussion

Beginning my experiment I couldn't find the ice cube trays that i needed, so I changed the shapes.

Benefit to Community and/or Science

Background Research

When water is frozen the molecules are stick together and become a solid. As the water heats up the molecules separate and become a liquid. Ice begins this process when it reaches zero degrees celcius.
